New amp. Help!

[cr4ck]

Okay, yesterday I just bought a new head and a new box. The head is a Ashdown ABM 500 EVO II, the Box is a Hughes&Kettner Quantum QS 2115 PRO.
It was necessary to bought this things, ‘cause in the rehearsal room I didn’t hear me.
(Before I played an Peavey Max 450 and the Cab was a Peavey 115BVX BW 8 ohm.)

I play an Ibanez SR505 which is an activ bass. So now I’ve the problem that I have very good lows but the high notes I don’t hear anymore.
I haven’t changed the battery in the Ibanez Bass since I bought it (9 months ago, or so…). Can that be the reason? Or how can I get a better sound of the highnotes whit this Amp? Or is it just the Amp?

Ah yes, sry for my bad english ;-)

Cheers.

Adjust the knobs on your bass. Adjust the EQ's on the head. Raise the treble and mids, and lower the bass.

Replace the battery too, it costs $3.

its probably the 2x15s thats causing you the problem - they will play the low end really well, but they wont handle the highs fantasticaly - buy a 2x10 to add to it (or do some other things that the other guy said)

I don't have 2x15s ;-) I've 2x10s... But do you really think the cab is the reason?
Have the Ashdown Heads speaker protections?

No I don't think it is.

The Peavey amp has a bit more treble in it's character and the Ashdown is a warmer amp (with more lows, a bit scooped highs and therefore sounding smooth).

Replace the battery and then check again. I think that's it. And boost the highs a bit if you don't hear them.

It's from the fundamentals of physics. The bigger the speaker, the lower the frequencies that can be put out clearer. Pushing out the higher frequencies forces more work upon a bigger speaker than it does a smaller speaker. It's not a big problem, it can be fixed with just turning down the bass a little and raising the mids and treble on the head.

That cab is nice, btw. 2x10s ans 1x15 all in one? Nice.

apologies, im a retard, read 2115 and assumed it was a 2x15 - i have learnt not to assume :(

Yeah when I saw that, i was like, "Holy sh*t! 2x15?! That's HUGE..."

I know a 15" cabinet which kills a 210 cabinet in the highs. WITHOUT a tweater.. :rolleyes:


Peavey BW 15" vs an ampeg classic 210. Then the peavey is the winner.. :p So what you say there doesn't work always, but is a nice indication ;)

grammar police! PULL OVER!

i think buying just 15's was a mistake. it's something i'd never do anyway, not w/o a 10 or a 12 with it.
